ENGLISH FUNCTION BUTTONS ON/OFF To Power ON the meter rotate the Function Selector switch from the OFF setting to any measurement setting. To Power OFF the meter rotate the Function Selector switch to the OFF setting. By default, the meter will automatically Power OFF after 30 minutes of inactivity. Reactivate meter by pressing any button.
FUNCTION BUTTONS "REL" (RELATIVE) BUTTON Relative measurements are available for Voltage, Current, Resistance, Temperature and Capacitance. 1. Perform first measurement. 2. With test leads connected, press REL to set frame of reference. 3. Perform second measurement. The value displayed is the difference between first and second measurements.

OPERATING INSTRUCTIONS CONTINUITY 1. Insert RED test lead into V jack , and BLACK test lead into COM jack , and rotate function selector switch to the Continuity/Resistance/Diode setting. NOTE: The meter defaults to Continuity testing in this mode. Ensure that the Continuity Testing icon is visible on the display.
ENGLISH OPERATING INSTRUCTIONS RESISTANCE MEASUREMENTS 1. Insert RED test lead into V jack , and BLACK test lead into COM jack , and rotate function selector switch to the Continuity/Resistance/Diode setting. NOTE: The meter defaults to Continuity testing in this mode. To enter Resistance testing mode, press the "SEL"...
OPERATING INSTRUCTIONS CAPACITANCE 1. Insert RED test lead into V jack , and BLACK test lead into COM jack , and rotate function selector switch to the Capacitance setting. Display should read 0 nF with leads open. 2. Remove power from circuit. 3.

ENGLISH OPERATING INSTRUCTIONS TEMPERATURE 1. Insert K-type thermocouple with adapter into the V and COM jacks (observe polarity markings on thermocouple and meter), and rotate function selector switch to the Temperature setting. NOTE: The meter defaults to Fahrenheit scale in this mode. To enter Celsius scale, press the "SEL"...
MAINTENANCE BATTERY REPLACEMENT When indicator is displayed on LCD, batteries must be replaced. 1. Remove screw from battery/fuse door. 2. Replace 2 x AAA batteries (note proper polarity). 3. Replace battery/fuse door and fasten securely with screw. FUSE REPLACEMENT A fuse may blow if more than 500mA is applied to the A/mA jack or more than 10A is applied to the 10A jack .
ENGLISH CLEANING Be sure meter is turned off and wipe with a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents. STORAGE Remove the batteries when meter is not in use for a prolonged period of time. Do not expose to high temperatures or humidity.
